Flat cable connectors to enter the axle of the motor

Flat cable connectors to enter the axle of the motor

MARKET NEED

With the rise of cargo bikes, E-MTB’s and +500Watt E-bikes, it’s obvious that the E-bike market is demanding more powerful motors. However, connectors that can handle more power are generally bigger and have thicker cables. 

When it comes to rear or front hub motors, this thicker cable must still enter the axle of the motor. That’s exactly where the difficulty arises. In the end, the cable diameter is just too thick to enter the axle of the hub motor.

CONNECTOR SOLUTION

The alternative that Higo has come up with is to use a flat cable. Instead of placing the wires around each other, Higo places them next to each other, thereby creating a compact flat version. Eventually, this flat cable has a section of 3x2,35mm²+7x0,14mm² and can therefore be more easily integrated into the motor design. In combination with a moulded, tailor made grommet, the wires on the inside of the motor will be properly sealed off and a waterproof (IP65) connection can be established.

With the ability to handle up to 30A, the flat cable connector version offers customers a solution when space is limited and power is still needed.
